摘　　要：要求一个循环过程的热效率,如果循环过程包含着线性过程,需要先求出线性过程热量转换点, 明确热量转换点两边的过程是吸热还是放热过程,再求出循环过程吸取的热量,才能求整个循环过程的热效率．To work out the efficiency of a thermodynamic cycle that includes linear processes, we shall first indentify the inversion points of these linear processes, then decide whether processes on either side of the spotted points absorb or exhaust heat, and finally, with heat absorbed during the whole cyclic process easily figured out, we are sure to arrive at our cycle efficiency.

关 键 词：热量转换点 循环 效率
